Systems Engineer - Enterprise Platforms (IAM & Automation)
Job Description
[Up to c. $375k Comp Package (or equivalent) | Hybrid Working]
Role Overview
We’re supporting a highly technical, engineering-led trading firm as it continues to scale its internal technology platforms. This role sits within the Enterprise Technology function - the group responsible for building and operating the systems that power employee productivity, access, and internal workflows across the firm. At its core, this is a hands-on systems engineering role. You’ll own and evolve internal platforms that span Linux-based services, automation tooling, SaaS integrations, and identity-aware workflows. While Identity and Access Management is a key domain, the focus is on engineering reliable systems, not policy or governance work. If you enjoy deep technical ownership, strong automation, and stitching together complex internal platforms with clean APIs, this role is designed for you...
Key Responsibilities
- Engineer and operate internal enterprise systems with a strong emphasis on Linux-based services and command-line operations
- Build and maintain Python-driven automation to streamline internal workflows, reduce manual effort, and improve system reliability
- Design, implement, and support integrations between internal systems and a broad SaaS ecosystem using APIs, webhooks, and event-driven patterns
- Own and improve identity-aware workflows, including authentication, access provisioning, and employee lifecycle processes
- Implement and maintain SSO and provisioning integrations using modern authentication standards and API-based models
- Administer and extend internal productivity platforms and enterprise SaaS tooling, acting as an engineering owner rather than a ticket handler
- Troubleshoot complex, cross-system issues spanning Linux hosts, application logs, identity flows, and third-party services
- Produce clear technical documentation covering system design, automation logic, and operational practices
- Break down ambiguous internal problems into robust, scalable solutions and communicate progress clearly to stakeholders
What You’ll Bring…
- 5-10 years of experience in systems engineering, internal platforms, or enterprise infrastructure roles
- Deep, hands-on Linux engineering experience, with confidence navigating the command line, debugging services, and analysing logs
- Strong Python development skills, used to build real automation, tools, or services - not just ad-hoc scripts
- Experience managing and integrating SaaS platforms in a production environment
- Solid understanding of IAM systems and authentication protocols, including how identity flows interact with real-world systems
- Proven experience working with APIs and system integrations, designing reliable connections between heterogeneous platforms
- Familiarity with Infrastructure-as-Code or configuration management tooling
- Comfort operating and improving systems that support joiners, movers, and leavers at scale
- An engineering mindset focused on reliability, simplification, and automation
- Ability to work independently on systems you own end-to-end, while collaborating effectively across teams
- (Preferred) Experience implementing or supporting SSO integrations for internally developed applications
- (Preferred) Exposure to security-adjacent IAM concerns (without being policy or compliance-led)
